More than a instructional activity, learners go through geometry topics example by example on the nicely organized handout. From postulates to classifying angles, there are rules and examples provided for each topic. The ten pages of...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Don't leave your classes in the dark! An inquiry-based lesson has young researchers analyze the light intensity before, during, and after a solar eclipse. They use their data to make inferences about the solar energy available during...

Don a hard hat and grab an iPad; both are essential tools for construction managers. A short video details the education, skills, and tools required for those interested in a career in this fast-growing field.

Does the explanation make sense? Sample items highlight claim three, communicating reason, in the Smarter Balanced assessments. Teachers use the 16 items to help show pupils the importance of communication and reasoning within...

Sometimes it's how you ask the question that counts. The sixth installment of nine from the Smarter Balanced Claim 1 Slideshow series presents a set of 13 questions to assess understanding of angle relationships as well as area and...

It is not as simple as scaling. MIT researchers explain that a micro engine cannot just be a proportional scaling of a working larger engine. The Math at the Core: Ratios resource compares the proportions involved with the surface area...

How can opposites be equal? Pupils learn about the measures of angles when two lines intersect by watching an educational video. They see how vertical angles are congruent, and solve problems using this idea.

Four angles hath quadrilaterals, but what be their measures? After watching a video, young mathematicians consider the interior angles of quadrilaterals. They see how to find missing angle measures using the properties of quadrilaterals.

Is there a resource that parallels the video? Scholars view a short video to review the types of angle relationships that exist when a transversal cuts two parallel lines. They watch as the narrator solves several problems involving...

Approach the instructional activity from the right angle. A discussion-based instructional activity leads helps learners understand angles in terms of rotation. Individuals use manipulatives to explore the properties of angles and learn...

Make Newton proud. Scholars apply their understanding of forces and energy to an engineering design challenge. They learn about simple machines, create a presentation on Newton's laws, and develop a balloon-powered car.

You can't go wrong with Star Wars! A video set to the Star Wars theme song presents a problem solving situation. The task? Determine how many small Post-It notes will fit on a bulletin board. The problem requires individuals to compare...

Investigate algebraic applications of complementary angles. Young scholars watch as the instructor describes and defines complementary angles. He then shows an example of finding an unknown value of x given expressions for a pair of...

A straightforward lesson explains the meaning of complementary and supplementary angles. The instructor uses both an algebraic representation and a numeric example to describe each angle pair.

Define angles across from each other. An informative segment from a larger playlist on geometry introduces vertical angles and shows they have equal measures. Using their properties, the presenter solves problems involving vertical angles.

Supplement your knowledge of angles. Part of a playlist exploring geometry concepts, an interesting video introduces the definition of supplementary angles. Using the definition, the presentation shows how to find the supplement to a...

Place angles in a line. Part of a playlist on basic geometry, an informative video teaches pupils the definition of a linear pair and how to identify them. Using their properties, the resource demonstrates how to solve problems involving...

Complement the angle definition. The resource, a video within a basic geometry playlist, introduces the definition of complementary angles. Using the definition, the presentation finds complements of given angles.

Complement and supplement your knowledge of angles. Young mathematicians study supplementary and complementary angle pairs using an interactive. A set of challenge questions solidifies this understanding.

Yo, yo, learn about vertical angles with a yo-yo. Using an interactive, scholars adjust the position of fingers holding a design from a yo-yo. Answering a set of challenge questions based on the interactive helps clarify understanding of...

Examine vertical angles from a different angle. Moving one line in an intersecting pair of lines lets users see relationships between vertical angles. They finish by answering some machine-scored questions on the topic.

Gain some perspective on linear pairs. Aspiring mathematicians adjust the vanishing point on a perspective drawing. They see the effect on linear pairs of angles and answer five challenge questions based on their observations.
